My invention relates to devices for emitting vaporous exhalations for any purpose for which fumi ants'are used, whether such exhalation be o ensive ortnoxious',.stifiing or irritating or merely .odorous as, for example, a perfume vapor.

Though my invention. in its concrete or structural form extends to and includes any and all of the numerous usesof which it is capable, its particular object for which it is, at present, intended', is as a fumigant against moths, it being to this end especially adapted for closets and other small,closed chambers in which clothes or fabrics are stored.

Briefly stated, .my invention, comprises a container adapted for convenient suspension ina closet, said housingor shell having fitted within it a vial containingza-va-pon e-Xhaling or volatile'substance, in this case, cedar oil, for example. From this oil leads a wick, by the. capillar attraction of which the oil is raised and al owed to volatilize as vapor which escapes, through openings in the container, into the closet. Means are provided for arresting the function of the wick when the device is not in use, and for conveniently restoring said function when vaporization is desired.

In the accompanying drawing to which reference is made, I have shown my device in its preferred form, though it is to'be understood that changes may be made therein without departing from the spirit of the 'invention as defined by the claims hereunto appended.

In the drawing Fig. 1 is a vertical sectional elevation of my vaporizing device.

Fig. 2 is a section on the line 22 of Fig. l.

1 1s a housing or shell; in practice, for example, a card-board carton, having openings 2 in its walls near its upper end, and

7 opening downwardly from its top. In this socket is rigidly fixed, by means of suitable v adherent, a bottle or vial 6 with a stopper 7 in its mouth.

In the vial is the vapor-emitting substance PATENT creme ABRAHAMJJ; nrcnrracr OAKLAND, cnmroanm indicatedby 8, which substance, as I have .here nabove stated is, or may be, for theuse intended, cedar-oil.

9 isa wick which, preferably, comprises several fiat strips side by side, making a 'relatively wide capacious capillary .conveyer. The lower end of the wick dips into the oil 8, and thence rises-between-the stopper Tand the vial neck, andhangs its upper end over said neck as shown at 9, to an extent suih- ,cient to prevent it from dropping into the vial when the stopper is loosened.

101s a pressure-resistant member in the form of a yoke or stirrup freely straddling the projecting upper end of the vial and its stopper, the top 'of said yoke bearing under a shield disk 11 lying between said top and the cap 3 of the carton, and its foot-extremit'ies being'firmly seated in the top of the to block 4. V

12is' an externally threaded post or stud passing freely through the carton" cap 3,

shield disk 11 and the top of the yoke 10. It

upon the top of the stopper 7.

is provided with. a flange 13 which bears Below this flange the-stud 12 isthreaded' as a wood screw 14 which penetrates the stopper and is preferably cemented thereto for fixed engagement therew1th,whileabove said flange itis thread- I ed' as a machine screw 15, which is fitted with a nut 16, bearing upon the carton cap 3, and

carrying asuspension ring 17. I

To charge the device, and prepare it for use, the vial 6 having been exposed and opened by the removal of theupper members including the stopper, or, for that matter, by the removal and disassembling of all the interior parts, block, vial and all, from the carton, the volatile substance 8 is supplied. Then the wick 9 is dipped in said substance j and carried up to hang over the bottle rim at 9'. The stopper 7 is thereupon fitted in the neck ofthe vial with pressure sufficient not only to close said neck, but also to compress the wick against the neck wall with such tightness that the capillary. function of said wick is practically destroyed and any seepage therethrough prevented. Then the yoke 10, q 7

stud 12 having been previously screwed into the stopper 7 until the flange 13 of the stud bears upon top of said stopper. The nut 16 is then fitted to the upper end 15 of the stud and turned down lightly upon the carton cap 3. The device is now hermetically sealed for transportation and storage. When ready for use, the nut 16 is turned down with increasing tightness until due to the resistance it meets with in the yoke 10 and block 4, it raises the stud 12, and thereby lifts the stopper 7 relieving the pressure upon the wick 9, thereby restoring the capillary function of said wick and allowing the oil 8 to seep up through the wick and be volatilized at the wick end 9' and pass out as vapor from the carton 1 through its holes 2. Then the device is hung up by the ring 17 in the closetor other chamber which it is desired to fumigate. The shield disk 11 is a guard for the carton cap against undue deterioration from the escapmg vapor a In order to shut off the operation of the device. and restore it to non-use, the nut 16 is turned upwardly upon the stud 12, and the latter is then manuallypressed down to again tighten the stopper in the vial.

hen the device is in use, and hanging from the ring 17 its weight is carried by'the nut 16 and stud 12 'the flange 18 of said stud bearing against the bottom of the yoke 10 and through it against the bottom of the can? Said cap fits the carton 1 tightly, and may if desired, be provided with any ordinary means for holding it thereupon, so that the weight of the carton, block, and vial can be suspended from it. The extent of movement of the stopper 7, before the flange 13 strike the bottom of the yoke 10, is sufficient to relieve the pressure upon the wick without freeing it so completely that it might drop down into the vial.

I claim v 1. A vaporizing device comprising an apertured shell; a block fitted therein; a vial for a volatile substance carried by said block; a wick dipping into the volatile substance and hanging over the mouth of the vial for exposing the seeping substance to evaporation; a stopper in the vial neck adapted by pressure upon the wick to control its capil lary function; and means for withdrawing the stopper to relieve its pressure upon the wick consisting of an axially movable flanged stud associated with the stopper; a nut threaded upon said stud for moving it; and a pressure resisting yoke carried by the block and bearing under said nut.

2. A vaporizing device comprising an apertured shell; a block fitted therein; a vial for a volatile substance carried bysaid block; a wick dipping into the volatile substance and hanging over the mouth of the vial for exposing the seeping substance to evaporation; a stopper inthe vial neck adapted by pressure upon the wick to control itscapillary functlon; and means for Withdrawing the stopper to relieve its pressure upon the wick consisting of an axially movable flanged stud associated with the stopper; a nut threaded upon said stud for moving it; and a pressure resisting yoke carried by the block and bearing under said nut; and a shield disk lying between the yoke and nut.

3. A vaporizing device'comprising a vial forcontaining a volatile substance; aholder for said vial; a wick dipping into the vola- .tile substance and extending through the mouth of the vial ;-a stopper in the vial neck adapted by pressure upon the wick to control its capillary function; and means for withdrawing said stopper to relieve its pressure upon the wick comprising an axially movable stud connected with said stopper, a nut threaded upon said stud for moving it, and a pressure resisting yoke straddling said stopper and resting upon the vial holder, said yoke bearing under said nut. v 4. A vaporizing device comprising a vial for containing a volatile substance; a holder for said'vial; a wick dipping into the volatile substance and extending through the mouth of the vial; a plug in the neck of the vial adapted both to seal said neck and to compress said wick to prevent its capillary function; and means carried by the holder for withdrawing said plug to relieve its pressure upon the Wick.

In testimony whereof I have signed my name to this specification.
